## **Description**

We only use this package for its types, so can be treated as a dev
dependency. This will also resolve the audit issue currently seen in
[CI](https://app.circleci.com/pipelines/github/MetaMask/metamask-extension/95274/workflows/b92333ec-1a1c-4ce6-bd7d-7601fe14e1e3/jobs/3546366).

Fixes: CI issues, and better reflects the use case of this dependency.

## **Manual testing steps**

Re-test notifications flow

1. Onboard with new or existing wallet
2. Enable notifications
3. Perform a swap on Polygon (a chain we support on-chain notifications
for)
4. See if notifications appear.

For Notification Devs: As there is no feature announcements yet,
manually change the code to point to a portfolio feature announcement.
I've tested and it seems that we still correctly show a feature
announcement to users.
